Linear dimming

LED module/LED driver/supply

8 – 9 mm

wire preparation:0.5 – 1.5 mm²

3.2 Wiring type and cross section

Solid wire with a cross section of 0.5 – 1.5 mm². Strip 8 – 9 mm of insulationfrom the cables to ensure perfect operation of terminals.

3.3 Loose wiring

Loosen wire through twisting and pulling or using a Ø 1 mm release tool

3.4 Wiring guidelines

• Run the secondary lines separately from the mains connections and lines to achieve good EMC performance.

• The max. secondary cable length is 2 m (4 m circuit), this applies for LED output as well as for I-SELECT 2.• For good EMC performance, keep the LED wiring as short as possible.• Secondary switching is not permitted.• The LED driver has no inverse-polarity protection on the secondary side. Wrong polarity can damage LED modules with no inverse-polarity protection.• Wrong wiring of the LED driver can lead to malfunction or irreparable damage.• In case of protection class II applications it’s recommended to separate the lamp wires of the different channels. Depending onto the luminaire construction additional actions, such as equipotential connection between driver and LED or a toroidal ferrite at the lamp wires are recommended.• To avoid the damage of the Driver, the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.).

3.5 Hot plug-in

Hot plug-in is not supported due to residual output voltage of > 0 V. If a LED load is connected the device has to be restarted before the output will be activated again. This can be done via mains reset or via interface (DALI, DSI, switchDIM).

3.6 Earth connection

The earth connection is conducted as protection earth (PE). The LED driver can be earthed via earth terminal or metal housing. If the LED driver will be earthed, protection earth (PE) has to be used. There is no earth connection required for the functionality of the LED driver. Earth connection is recommended to improve following behaviour:• Electromagnetic interferences (EMI)• LED glowing at stand-by• Transmission of mains transients to the LED output

In general it is recommended to earth the LED driver if the LED module is mounted on earthed luminaire parts respectively heat sinks and thereby representing a high capacity against earth.

3.7 I-SELECT 2 resistors connected via cable

Make sure that the LED driver is operated within the given window under all operating conditions. Special attention needs to be paid at dimming and DC emergency operation as the forward voltage of the connected LED modules varies with the dimming level, due to the implemented amplitude dimming technology. Coming below the specified minimum output voltage of the LED driver may cause the device to shut-down. See chapter “6.9 Light level in DC operation” for more information.

5. Software / Programming / Interfaces

5.2 Control input DALI

The control input is non-polar for digital control signals (DALI). The control signal is not SELV. The control cable has to be installed in accordance to the requirements of low voltage installations.

Digital control with:• DALI signal: 16 bit• DSI signal: 8 bit

5.1 Software / programming

With appropriate software and interface different functions can be activated and various parameters can be configured in the LED driver.The Driver supports the following software and interfaces:

Software / hardware for configuration:• companionSUITE (deviceGENERATOR, deviceCONFIGURATOR,

deviceANALYSER)• masterCONFIGURATOR

Interfaces for data transfer:• Control input DALI

5.3 I-SELECT 2

By inserting a suitable resistor into the I-SELECT 2 interface, the current value can be adjusted. The relationship between output current and resistor value can be found in the chapter “Accessories I-SELECT 2 Plugs”. If the resistor is connected by wires a consistent base insulation must be ensured. Furthermore, a max. wire length of 2 m may not be exceeded and potential interferences have to be avoided.

Resistors for the main output current values can be ordered from Tridonic (see accessories).

6.3 LED current

The LED output current must be adapted to the connected LED module.The value is limited by the current range of the respective device.

The output current of the LED driver can be adjusted in a certain range. For adjustment there are 4 options available.

Option 1: DALI Adjustment is done by companionSUITE or by masterCONFIGURATOR.

Option 2: I-SELECT 2 By inserting a suitable resistor into the I-SELECT 2 interface, the current value can be adjusted.

The priority for current adjustment methods is DALI (highest priority) and I-SELECT 2 (lowest priority).

6.1 OEM Identification

The OEM (Original Equipment Manufacturer) can set his own identification number.DALI Part 251: Memory bank 1 extension.

6.2 OEM GTIN

The Original Equipment Manufacturer (OEM) can set his own Global Trade Item Number (GTIN).DALI Part 251: Memory bank 1 extension.

6.4 Device operating mode

A Tridonic Driver supports several control signals. These control signals are automatically detected and the mode is adapted.If only one special device mode is required, this mode can be selected.“Automatic detection” is the default setting.

6.6 corridorFUNCTION

With the corridorFUNCTION and a commercially available motion detector, it is easy to adapt the lighting in one area to its use. That is, when the area is entered by a person, the lighting dims instantly to the desired brightness and is available in full strength. After the area is left by the person, the brightness dims slowly to a smaller value or switches off completely. The individual parameters of the desired profile, such as brightness values or delay times, can be adjusted flexibly and individually.

6.7 Constant Light Output (CLO)

With this function the light output of the LED module can be kept equal over the lifetime.The light output of an LED module reduces over the course of its lifetime.The Constant Light Output (CLO) function compensates for this natural decline by constantly increasing the output current of the LED driver throughout its lifetime.CLO shall be achieved by limitation of the LED current at the commissioning of the LED driver and providing a linear interpolation of the current over the time, depending on the data points given by the user.

6.5 switchDIM

Integrated switchDIM function allows a direct connection of a pushbutton for dimming and switching.Brief push (< 0.6 s) switches LED driver ON and OFF. The dimm level is saved at power-down and restored at power-up. When the pushbutton is held, LED modules are dimmed. After repush the LED modules are dimmed in the opposite direction.In installations with LED drivers with different dimming levels or opposite dimming directions (e.g. after a system extension), all LED drivers can be synchronized to 50 % dimming level by a 10 s push.Use of pushbutton with indicator lamp is not permitted.



LED driver

Linear dimming

The LED driver is designed to operate on DC voltage and pulsed DC voltage. For a reliable operation, make sure that also in DC emergency operation the LED driver is run within the specified conditions as stated in chapter “4.1 operating window”. Light output level in DC operation: programmable 1 – 100 % (factory default = 15 %, EOFi = 0.13).

The voltage-dependent input current of Driver incl. LED module is depending on the used load.

The voltage-dependent no-load current of Driver (without or defect LED module) is for:AC: < 21.8 mADC: 5 – 7 mA

In DC operation dimming mode can be activated.If Dimming on DC is activated the requirements of the DC recognition function are ignored.Even if DC is detected, the LED driver continues to behave as in AC mode

• The present dimming level is retained• An emergency light level defined for the DC recognition function (DC level) is ignored• Control signals via DALI continue to be executed

If Dimming on DC is activated then emergency mode is not recognised. The device no longer automatically switches to the emergency light level.

6.8 DC operation

In emergency light systems with a central battery supply the DC recognition function uses the input voltage to detect if emergency mode is present. The LED driver then automatically switches to DC mode and dims the light to the defined DC level.Without DC recognition different and more complex solutions would have to be applied in order to detect emergency mode.DC recognition is integrated in the device as standard. No additional commissioning is necessary for activation.

This is a safety-relevant parameter.The setting is relevant for the dimensioning of the central battery system.

6.9 Enhanced power on level (ePOL)

The Enhanced Power On Level parameter defines the power level that is set automatically when power is restored after a power failure.The Enhanced Power On Level can be set to a fixed value (0 – 100 %) or can recall the memory value.The memory value is the last value the LED driver was set to before the power failure.This value applies not only in DALI device operating mode, but also in the device operating mode switchDIM.

6.13 Power-up fading

The power-up function offers the opportunity to modify the on behavior. The time for fading on can be adjusted in a range of 0.2 to 16 seconds. According to this value, the device dims from 0 % up to the power-on level. By factory default no fading time is set (= 0 seconds).

6.10 DALI default parameters

In order for all luminaires to react the same for each operation (switching, dimming, scene recall ...), these values must be set the same.These DALI standard parameters are supported by every DALI-2 device.

6.11 Scenes and groups

Each device can be a member of up to 16 groups.Also, 16 different scene values can be stored in each device.

6.14 Dimming curve

DALI:The desired dimming behaviour is selected via two different dimming curves (logarithmic or linear).The default setting of the dimming behaviour is logarithmic.

6.15 Colour temperature range

Here you can define the usable colour temperature range.The colour temperature is limited by the physical upper and lower limits of the connected LED module.

6.12 fade2zero

When the Driver is switched off, fade2zero allows a smooth dimming down to almost zero.Activate the fade2zero function when programming with companionSUITE and set a DALI fade time. fade2zero only works if the minimum dimming level of the Driver is the default value.The device then dims to far below the limit of its working window (dimming range).This function is deactivated by default.

7. Protective features

7.2 Intelligent Voltage Guard (IVG)

The Intelligent Voltage Guard (IVG) function warns of possible damage due to overvoltage or undervoltage.The mains voltage is constantly monitored and if necessary appropriate responses are made:

• If the mains voltage is too low (< 70 V), the LED driver is switched off.• At a mains voltage between 70 and 140 V, the LED driver switches off and on again on a non-cyclic basis.• In case of an overvoltage (> 318 V), the LED driver sends feedback via DALI.

In case of a short-circuit at the LED output the LED output is switched off. After restart of the LED driver the output will be activated again. The restart can either be done via mains reset or via interface (DALI, DSI, switchDIM).

7.5 Overload protection

If the maximum load is exceeded by a defined internal limit, the LED driver turns off the LED output. After restart of the LED driver the output will be activated again. The restart can either be done via mains reset or via interface (DALI, DSI, switchDIM).

7.4 No-load operation

The LED driver will not be damaged in no-load operation. The output will be deactivated and is therefore free of voltage. If a LED load is connected the device has to be restarted before the output will be activated again.

7.1 Intelligent temperature guard (ITG)

The Intelligent temperature guard (ITG) function provides effective protec-tion against thermal overloads by slowly reducing the output if a defined internal temperature is exceeded.The reduction of overtemperatures takes place in small steps every two minutes. As soon as the temperature drops again, the output power is gradu-ally increased every 10 minutes. On DC operation this function is deactivated to fulfill emergency requirements.

6.16 Channel grouping

With this, the number of output channels can be split / grouped differently.This is important for the control of the device. The physical LED outputs are assigned to different logical units (DALI addresses).

6.17 colourSWITCH

colourSWITCH is an extension of switchDIM.You can call up to 9 predefined colour temperature values.With a short press via a pushbutton on terminal CS, the 9 predefined colour temperatures can be called up in succession.With a long press via a pushbutton on terminal CS, the colour temperature is continuously adjusted.

In installations with LED drivers with different colour temperature or opposite colour temperature directions (e.g. after a system extension), all LED drivers can be synchronized to 4,500 K by a 10 s push.

A conventional pushbutton can be used to control the system via colourSWITCH. Use of pushbutton with indicator lamp is not permitted.If the device is controlled via DALI/DSI, colourSWITCH is not available.

8.2 Conditions of use and storage

Humidity: 5 % up to max. 85 %, not condensed (max. 56 days/year at 85 %)

Storage temperature: -40 °C up to max. +80 °C

The devices have to be acclimatised to the specified temperature range (ta) before they can be operated.

The LED driver is declared as inbuilt LED controlgear, meaning it is intended to be used within a luminaire enclosure.If the product is used outside a luminaire, the installation must provide suitable protection for people and environment (e.g. in illuminated ceilings).

8.1 Insulation and electric strength testing of luminaires

Electronic devices can be damaged by high voltage. This has to be considered during the routine testing of the luminaires in production.

According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A, each luminaire should be submitted to an insulation test with 500 V DC for 1 second. This test voltage should be connected between the interconnected phase and neutral terminals and the earth terminal. The insulation resistance must be at least 2 MΩ.

As an alternative, IEC 60598-1 Annex Q describes a test of the electrical strength with 1500 V AC (or 1.414 x 1500 V DC). To avoid damage to the electronic devices this test must not be conducted.
